What is (-i)³?
Correct answer gets pinned.

D

Step-by-step explanation:

D. i

Step-by-step explanation:

When putting i to a power, there is a rule.

i¹ = i

i² = -1

i³ = -i

i⁴ = 1

And it repeats again, such as:

i⁵ = i

i⁶ = -1

And so forth.

This rule also applies to -i, but the values are slightly different:

(-i)¹ = -i

(-i)² = -1

(-i)³ = i

(-i)⁴ = 1

And that one keeps repeating such as

(-i)⁵ = -i

(-i)⁶ = -1

And so forth.

So to answer your question, (-i)³ = i.

$12. that is my answer.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
